The cell is the basic unit of life Cell Membrane Nucleus Nucleolus Mitochondrion Golgi Rough ER Smooth ER Lysosome Vacuole
The Nucleus contains the cell’s genetic material (genome) Genetic material in the form of DNA Molecules are organized into structures called chromosomes HeLa cells stained with Hoechst dye for DNA
